Am in the process of deciding on either of these two variants.
Have zero experience with these COD engines, actually only found out about them today truth be told
Now the woman likes a little bit of poke, as we currently have a 2009 1.8tfsi
And thought we'd decided on the 2.0tdi, now the saleswoman in my local audi has proclaimed that this little 1.4 150hp will easily be as quick as our 1.8 were used to???
Im assuming that with a 4 body load, the little 1.4 will fall on its a$$, but i'm willing to be told straight if not
Whats the verdict chaps?
 
Can't really comment on the comparison, but the 1.4 COD goes plenty fast enough for me.
I would think that the mileage you plan should be a big factor in your decision. Upto 15k per annum - petrol. Over that diesel makes some sense.
 
Just seeing if anyone has a real world comparison of how much slower the 150 1.4 is to our current 1.8tfsi
 
I have a TT with the 1.8TFSI engine as well as the A3 with 1.4COD 150. I have to say that there is little if any difference in the performance between the two cars. The TT feels different (it has 19" wheels). Both have the 7-speed STronic gearbox. Don't be misled by the fact that it's a 1.4 engine. It's VERY sprightly and just soooooo smooth and quiet. I love mine!
 
Book a test drive, I think you'll be pleasantly surprised how much performance you can get out of the 1.4. Pair it with an S Tronic and it's a joy to drive. It's a very smooth engine, very quiet but with a nice sporty note when accelerating. I drive mostly in S mode now as it suits my driving style and the country roads to work, even with an aggressive 20 mile drive to work I'm achieving 44MPG consistently. I've had it over 55MPG when being sensible.
 
I have the 2.0L TDI 150 and then had a go in the cod. I was really impressed by it and wonder why I went diesel for my 8k a year. It's such a smooth engine, really quiet and has some nice power/acceleration in the lower gears.
 
Cheers for that rob, does the 1.4 pull fine enough when the cars full?

I have the 1.4 sport as my company car. I do approx 30k a year.

We have a limited list of cars on our list. It included the 1.6tdi sport and 2.0tdi SE.

I was lucky to persuade the fleet manager to add the 1.4 sport from her big list.

Reason for picking this engine low CO2 @ 109 so low tax plus petrol does not have the 3% surcharge that diesels attract.

My company pays all my fuel so my tax for this is fixed regardless of my personal mileage.

My priority was a well spec'd car, the Sport over SE has more spec and Sline was not available. I also wanted a nice engine with power and smooth. My last company car at my last place a 116ed was efficient but diesels are still not as smooth as petrol.

I ordered the car without a test drive because I couldn't get one organised.

It turned up and it was amazing, especially coming from a Mercedes A180 CDI. It pulls really well, it's a lot smoother than a diesel and my tax is pretty low. It copes a lot better than a diesel in 2nd gear no juddering just smoothness lol.

I've had 2.0tdi as courtesy and it was not a patch on the 1.4. The noise the vibrations were noticeable and it felt heavy. As soon as I got back in mine I knew I made the right choice.

I keep recommending this engine to everyone. Mine has 140bhp I had a 150bhp as courtesy for a service and the extra 10bhp made it even better.

Spec wise I have a few options the best is radar cruise. Even in a manual it makes perfect sense it's great on motorways, A road following people, country lanes with annoying drivers. Every situation you can use radar it makes driving so much more stress free. I had this my accident as the fleet manager miss understood what I wanted and it was the best mistake ever!

And delete sport suspension it adds to stress free motoring

My next car is going to hopefully be a 1.4 saloon auto S Line.

Forgot to add I've had the car 5 up and it still pulls really well. I regularly have my boot full of work stuff and it beats lots of things off the line lol

I only tried it with myself in the car but it felt like a mini sports car compared to mine as the acceleration is so good. The diesel is a nice engine compared to ones I've had before, but my next one will probably be the petrol with sports suspension.
Everyone has a different view so best to try one and see what you think.

Nope, still quick enough with four adults and their luggage...
 
Had the 150TDI in my last 8V and changed to the 150COD this time around. Only do around 9k miles a year and the vast majority of that is urban driving where diesel doesn't really help with economy. Combined with the company car tax savings mentioned above, I figured it was time to go back to petrol after 17 years.

Haven't looked back. The petrol has ample performance and the economy is pretty darn good. I get around 32mpg in purely urban driving with loads of stop/start at traffic lights and junctions and average 50mpg on a long run. At a constant 70mph motorway run, I've managed 60mpg. Yes the diesel will better those figures but not by much, especially in town.

The refinement issue also can't be overstated. I don't care how refined modern diesels are, they still sound like buses compared to petrols. It's obviously quieter and more refined inside the cabin but what really struck me was the first time the good weather arrived and I was cruising around town with the windows down. Not having to listen to your own diesel chatter every time you stopped in traffic or it reflected off a build or car you were passing was just sooo nice.
 
I've had my 1.4 COD 150 S-tronic for a month now, and I can't get enough. It does want to start off standstill in second gear when in efficiency mode, but its not an issue unless you want to play, and then you can switch mode, work the paddles and/or use s-mode pullback. In high gears low revs its just smooth and comfy, and you suddenly realize you hit the speed limit without noticing.

In high revs lower gears it gives satisfactory pull when pressing the gas pedal, and its a surprisingly welcome change from the usual low-rev driving.

The engine has got enough power to give some driving fun when you want, and is very comfortable and silent in comfort/efficiency mode. When flooring it, its most fun from low speed - it doesn't give you that continuous G-force pull of a high-power engine, but enough to do a distinct takeover on the freeway.
Speaking of flooring it - I usually never floor it, but give just enough gas to achieve the acceleration - which really feels better - flooring it and not getting the proportional response is a bad practice for a car that can't deliver proportional power, its much more fun trailing the pedal to the power.

It continuously lures me into trying to be as efficient as possible, and I find myself striving for the "2-cylinder mode" alert and high mileage readouts.

And - ACC, or radar cruise control, is just phenomenal, With S-tronic it also does stop-and-go, but then it's a just a tad heavy on the braking.

Ssh, if you mention 60mpg with this engine the mpg police will be after you ;-)
 
Had the same issue and went for the 150 diesel, I get it on Monday.

Drove both, cod is very sprightly and smoother but diesel has more power and pull mid range. I went with diesel as I got a better deal on PCP and I could get it earlier.

The whole has to be over 15k to make a difference is rubbish mind. My cousin had a 184 q3 and her average mpg is 52, mine is 37 and we both do similar miles.

If petrol was cheaper on PCP and I could have got it as quick I would have went for it but after test driving them back to back it still doesn't have the torque 'kick' which makes the diesel fun at speed.

LOL - I've been there and done it, the diesel zealots can ramble on about how impossible it is all they like :p

It's not the total mileage but rather the nature of it that matters. The reason people say you don't benefit much from diesel if you only do low mileages isn't because of the low miles per se but rather that, in general, most of them are done in urban environments with lots of acceleration and braking, rather than higher speed cruising. In these environments, the economy advantages of diesels are far less marked.

Of course there are a myriad of factors to consider besides economy, such as power, torque, price, residuals, tax etc etc etc. What's right for one person won't necessarily be right for another :)
 
Well I've got the diesel now.

Things I like:

-power in any gear. The 1.4 122 is all about 1st, 2nd, 3rd where this is everything from 2nd - 6th. Accelerating 70-90 in 6th (on a private road) is very quick.
- smooth and very quiet. Same shifts as before and just as smooth as before in anything from 2nd upwards.
-fuel economy. Averaging 48 mpg and did a run to York today and the trip mpg was 55mpg. I rarely went below 70mph and certainly wasn't careful on the accelerator. My average mpg in the petrol was 37 and a trip like today would be 38-39mpg.
-power increase. In 3rd gear especially the torque really gets you forward very quickly. Overtaking is effortless

Things I don't like:

-1st gear. Feel the need to get out of it quickly and like I'm constantly going to stall it. Once out feels very similar to before in shifts etc
-not as quiet. Only really notice this on start up. Sat in traffic when I first took it home and didn't t notice the difference. Once it warms up it seems fine but sounds like a tank when you first start it up.

Overall very pleased and I'm noticing increased power and economy over a slight ly noisier engine on start up.

By the way when I test drive a car I always look at average mpg on the trip. Diesel I test drove was 50mpg and cod was 39mpg. I don't think sales agents care about economy (could be wrong) but that was again telling in me not wanting to wait 3 months. Treat the cod like an old man and get the economy, treat the diesel anyway you want and still get it.
 
In the real world I think there's very little difference in mpg between the 122 and the 140.

However the extra torque certainly is noticeable.
 
I test drove both and prefer the 1.4.

Generally the diesel feels like it has more low-end grunt but it didn't feel as smooth and I totally agree with one of the earlier comments - it feels "heavy".

I have the 1.4 as a company car but is also for personal use. Went for the S-Line (with S-Line suspension) - standard 18"s - so the ride is a little jarring at times on bad roads.

I've never found it lacking in speed but - and I think this is an issue with my car (and a few others) - I noticed the throttle is quite dull when setting off. I press it a little - nothing, press it a bit more - a little bit of movement, press it harder - wheel spin, engine noise and you fly off.

Other than that it's great. The engine is deathly quiet - even standing outside. Still - the thought that it's a 1.4 leaves a slight bitter taste when telling people what the engine is - unless you point out that it has 150 brake.

Does it come standard with 140??

Quite true, but to look down at the mpg displayed figures on two showroom test vehicles isn't objective at all....
 
In mainland Europe all these comparison are often quite pointless because diesel is around 20p per litre cheaper than petrol. So with a diesel you get better mpg and the fuel costs less. So if fuel efficiency is you thing it's a 'no brainer'. Why cannot the UK be the same.

If only. I seem to see a lot of blame on previous Governments encouraging people to buy diesels. It used to be significantly cheaper than petrol back then.

Now it's more expensive and, on top of that, there have been a few rumours/BBC article about an extra tax or some sort of charge for diesel cars - ridiculous!

The main reason I went petrol is that I hate the sound of a diesel engine.
 
From what I recall, in mainland European countries like France the governments have said they are going to be gradually raising the taxes on diesel and have said that it was mistake to promote its use over petrol so the price difference on the continent may be looking more like here in the UK in a few years :/
 
They initially encouraged diesel over petrol (via car and p11d tax) because of the obsession with CO2 emissions.
Now they realise that was a mistake because it's the diesels that kick out more particulates and mess up the kid's asthma etc. But it really isn't cars that are at fault for any of it really - buses and trucks in cities are the real culprits.
 
Well car went back in yesterday for 3 hours to get sat nav fitted. Guess what car I got as courtesy ? A3 1.4 150 cod!

Car had 3400 miles and average mpg was 37.4. My average mpg is 49.5 And I'm a fast driver.

Anyway onto the drive. Cod much faster in 1st gear and obviously quieter on start up. Lacks the torque punch of the diesel in anything from second gear going upwards. Didn't feel any different to drive and I know it is lighter but it didn't feel it?

Give them both a blast on the same stretch of road about half an hour apart and the diesel 'feels' reassuredly more powerful(probably to do with the torque) but obviously doesn't Rev as high before a gear change.

Going back to what I'd choose if no wait and the monthly payment reflected the cod's actual value ( I got the diesel 3 months earlier and pay a £1 less a month for a more expensive car) is a tough one.

I'm from petrol background and honestly I'd probably have chosen the cod as its familiar and a lovely quick engine. Cod quicker off the mark in first due to higher Rev count etc etc.

However, having driven the diesel and spent time with it I'm loving the extra mpg and it is significantly higher than the 3 cods I've driven. (Roughly 12 mpg more) I also love the torque and it gives you that feeling of power on tap in any gear which the cod just doesn't seem to do without a shift down.

The refinement and engine noise is a non entity. Only on start up do you notice any difference. Once you get going the diesel is just as quiet.

Like I've said before it's all objective and there are good reasons for buying both. You wouldn't go wrong with either!
 
Interesting! 37 seems low for the cod? I got about 48 on my test drive and that wasn't hanging around. I often get 49 on my diesel and thats why I was interested in the petrol.
I have found after 2 years it isn't quite as nippy as it used to be and the engine has that typical diesel noise I've had on other cars, which it didn't in the first year. Maybe it needs a really good long blast but I just can't do that living where I do.
 
49.5mpg on my 12 mile commute this morning in the 150 COD. Normal driving, mixture of A roads and town driving. On my previous 2.0tdi the same journey would be around 58mpg, so really not a great difference and the COD is waaaaay more nippy and responsive around town.

I agree. All new cars have to have engines that meet the EU6 regulations. I'm sure that there are a lot of old diesel cars and even more buses, vans and trucks where their engines are no where near this standard. In Germany they do not allow any vehicles that do not have a EU6 compliant engine in to most cities and large towns. Perhaps it's about time we did the same as it's mostly in the confines own towns that the air quality is a problem. Next year they will probably find something in petrol exhaust that increases the risk of cancer or something and it will all go full circle again.
 
I have driven both the 2.0l diesel and of course my car I find the diesel is far more clattery from inside the cabin at any rpm, plus the engine feels rather poderous compared to the 1.4. The diesel also has far too much turbo lag and a narrow torque range. However it is down to what driving conditions you use the car for, as I have already stated. The diesel encourages lazy driving on a motorway, because the engine will be within the turbo and torque range. But the 1.4 is a gem around town and on 'A' roads as it has the same torque as the 1.6 diesel but more power and a greater rpm and torque range.

I assume you read the consumption from the DIS. Remember this was a courtesy car and will have been caned by drivers trying it out. Yours is your own consumption which will reflect your driving style. My 150 COD has done 40.1 mpg from new (7000 miles) and that's a brim to brim figure.

Interesting comments. The 40 mpg on the cod after 7000 miles sounds realistic.
the comment about the diesel changing after a year could explain why I'm enjoying it right now and not finding it that much different?

Also don't Audi constantly update and amend their engines, which could explain why I'm not having issues that people with previous diesels did?

My journey to work is either dual carriageway or b roads depending if I'm dropping my daughter off. Been doing mostly B roads and my mpg to work has been 49, in previous car would have been 34.

We could go on forever so I'm bowing out and just saying they're both decent options and go with the best deal!!
 
I get about 40mpg - sometimes 37mpg - on my COD. That's a mixture of town, motorway and A roads...however, in Watford anyways, there is a lot of stop-start driving (e.g. 70mph - traffic light - 70mph - traffic light - 50mph - roundabout - etc.) so that probably kills my economy.

Still - it's surprisingly low to me but, thanks to COD and clever lab-based tests...109 CO2 emissions tricks HMRC into thinking it's a low emissions car when it probably isn't. In hindsight I still would've picked the 1.4 TFSI since it felt lighter, nippier and I'm not a fan of diesels unless they're BIG engines in an A6 or Q7.

In even more deeper hindsight I would've sacked both off and taken an eTron. 39 g/km CO2, 0-60 is quick and tax is so cheap I could've kitted it out with every option in the book and it'll still be cheaper than the COD (for company car leasing). Oh well - still happy.
 
I went from a 140ps 2.0tdi 8p to a 150ps 1.4tfsi COD 8v.

And I miss the diesel.

The COD economy on short trips at low speed is impressive, and the weight saving is good. But the torque is so much less that it feels much slower in the real world - I'm definitely not pulling away out of roundabouts like I used to. It's also so smooth with the power delivery that it doesn't feel that fast at higher revs, unless you've dropped a gear or are pulling away in 1st, which is so low geared it's too easy to spin the wheels.

And with a car load it's definitely slower.

But.. for a 1.4 petrol it's nice. It feels like a small diesel at low revs, which is no bad thing for the most part, with the flexibility to drop a cog and it turns into what feels more like a petrol. I think I prefer larger engines though.

Obligatory MPG comment: My commute I got 55-60mpg on the 2.0tdi (100,000 old). With a 5k old COD I'm getting 45mpg average (tank to tank - the on board computer is wildly over-optimistic claiming over 50mpg)
